Ferner können die erhaltenen Verbindungen der allgemeinen Formel I, wie bereits eingangs erwähnt wurde, in ihre Enantiomeren und/oder Diastereomeren aufgetrennt werden. So können beispielsweise cis-/trans-Gemische in ihre cis- und trans-Isomere, und Verbindungen mit mindestens einem optisch aktiven Kohlenstoffatom in ihre Enantiomeren aufgetrennt werden.Furthermore, the compounds obtained general formula I, as already mentioned at the beginning, be separated into their enantiomers and / or diastereomers. So can for example cis / trans mixtures in their cis and trans isomers, and compounds with at least one optically active carbon atom be separated into their enantiomers.

So lassen sich beispielsweise die erhaltenen cis-/trans-Gemische durch Chromatographie in ihre cis- und trans-Isomeren, die erhaltenen Verbindungen der allgemeinen Formel I, welche in Racematen auftreten, nach an sich bekannten Methoden (siehe Allinger N. L. und Eliel E. L. in "Topics in Stereochemistry", Vol. 6, Wiley Interscience, 1971) in ihre optischen Antipoden und Verbindungen der allgemeinen Formel I mit mindestens 2 asymmetrischen Kohlenstoffatomen auf Grund ihrer physikalisch-chemischen Unterschiede nach an sich bekannten Methoden, z.B. durch Chromatographie und/oder fraktionierte Kristallisation, in ihre Diastereomeren auftrennen, die, falls sie in racemischer Form anfallen, anschließend wie oben erwähnt in die Enantiomeren getrennt werden können.For example, the obtained cis / trans mixtures by chromatography in their cis and trans isomers, the compounds of the general formula obtained I, which occur in racemates, according to methods known per se (see Allinger N.L. and Eliel E.L. in "Topics in Stereochemistry", Vol. 6, Wiley Interscience, 1971) in their optical antipodes and compounds of general Formula I based on at least 2 asymmetric carbon atoms their physico-chemical differences according to known Methods, e.g. by chromatography and / or fractional crystallization, into their diastereomers, which, if in racemic Form, then as mentioned above can be separated into the enantiomers.

Die Enantiomerentrennung erfolgt vorzugsweise durch Säulentrennung an chiralen Phasen oder durch Umkristallisieren aus einem optisch aktiven Lösungsmittel oder durch Umetzen mit einer, mit der racemischen Verbindung Salze oder Derivate wie z.B. Ester oder Amide bildenden optisch aktiven Substanz, insbesondere Säuren und ihre aktivierten Derivate oder Alkohole, und Trennen des auf diese Weise erhaltenen diastereomeren Salzgemisches oder Derivates, z.B. auf Grund von verschiedenen Löslichkeiten, wobei aus den reinen diastereomeren Salzen oder Derivaten die freien Antipoden durch Einwirkung geeigneter Mittel freigesetzt werden können. Besonders gebräuchliche, optisch aktive Säuren sind z.B. die D- und L-Formen von Weinsäure oder Dibenzoylweinsäure, Di-O-p-toluoyl-weinsäure, Äpfelsäure, Mandelsäure, Camphersulfonsäure, Glutaminsäure, Asparaginsäure oder Chinasäure. Als optisch aktiver Alkohol kommt beispielsweise (+)- oder (–)-Menthol und als optisch aktiver Acylrest in Amiden beispielsweise (+)- oder (–)-Menthyloxycarbonyl in Betracht.The separation of enantiomers is preferably carried out by column separation on chiral phases or by recrystallization from an optically active solvent or by reaction with an optically active substance which forms salts or derivatives such as esters or amides, in particular acids and their activated derivatives or alcohols, and separating the diastereomeric salt mixture or derivative obtained in this way , for example due to different solubilities, it being possible for the free antipodes to be released from the pure diastereomeric salts or derivatives by the action of suitable agents. Particularly common, optically active acids are, for example, the D and L forms of tartaric acid or dibenzoyl tartaric acid, di-op-toluoyl tartaric acid, malic acid, mandelic acid, camphorsulfonic acid, glutamic acid, aspartic acid or quinic acid. Examples of suitable optically active alcohol are (+) - or (-) - menthol and optically active acyl radicals in amides are, for example, (+) - or (-) - menthyloxycarbonyl.

Desweiteren können die erhaltenen Verbindungen der Formel I in ihre Salze, insbesondere für die pharmazeutische Anwendung in ihre physiologisch verträglichen Salze mit anorganischen oder organischen Säuren, übergeführt werden. Als Säuren kommen hierfür beispielsweise Salzsäure, Bromwasserstoffsäure, Schwefelsäure, Methansulfonsäure, Phosphorsäure, Fumarsäure, Bernsteinsäure, Milchsäure, Zitronensäure, Weinsäure oder Maleinsäure in Betracht.Furthermore, the compounds obtained of the formula I in their salts, in particular for pharmaceutical use in their physiologically tolerable Salts with inorganic or organic acids. Come as acids therefor for example hydrochloric acid, Hydrobromic acid, sulfuric acid, methanesulfonic acid, phosphoric acid, fumaric acid, succinic acid, lactic acid, citric acid, tartaric acid or maleic into consideration.

Außerdem lassen sich die so erhaltenen neuen Verbindungen der Formel I, falls diese eine Carboxygruppe enthalten, gewünschtenfalls anschließend in ihre Salze mit anorganischen oder organischen Basen, insbesondere für die pharmazeutische Anwendung in ihre physiologisch verträglichen Salze, überführen. Als Basen kommen hierbei beispielsweise Natriumhydroxid, Kaliumhydroxid, Arginin, Cyclohexylamin, Ethanolamin, Diethanolamin und Triethanolamin in Betracht.In addition, the so obtained new compounds of formula I, if this is a carboxy group included, if desired subsequently in their salts with inorganic or organic bases, in particular for the pharmaceutical application in their physiologically acceptable Salts, transfer. As bases come here, for example, sodium hydroxide, potassium hydroxide, arginine, Cyclohexylamine, ethanolamine, diethanolamine and triethanolamine in Consideration.

Die biologischen Eigenschaften der neuen Verbindungen wurden wie folgt geprüft:
Die Fähigkeit der Substanzen und ihrer entsprechenden Salze, die DPP-IV Aktivität zu hemmen, kann in einem Versuchsaufbau gezeigt werden, in dem ein Extrakt der humanen Koloncarcinomzelllinie Caco-2 als DPP IV Quelle benutzt wird. Die Differenzierung der Zellen, um die DPP-IV Expression zu induzieren, wurde nach der Beschreibung von Reiher et al. in einem Artikel mit dem Titel "Increased expression of intestinal cell line Caco-2" , erschienen in Proc. Natl. Acad. Sci. Vol. 90, Seiten 5757–5761 (1993), durchgeführt. Der Zellextrakt wurde von in einem Puffer (10 mM Tris HCl, 0.15 M NaCl, 0.04 t.i.u. Aprotinin, 0.5% Nonidet-P40, pH 8.0) solubilisierten Zellen durch Zentrifugation bei 35,000 g für 30 Minuten bei 4°C (zur Entfernung von Zelltrümmern) gewonnen.
The biological properties of the new compounds were tested as follows:
The ability of the substances and their corresponding salts to inhibit DPP-IV activity can be demonstrated in an experimental setup in which an extract of the human colon carcinoma cell line Caco-2 is used as the DPP IV source. The differentiation of the cells to induce the DPP-IV expression was carried out according to the description by Reiher et al. in an article entitled "Increased expression of intestinal cell line Caco-2", published in Proc. Natl. Acad. Sci. Vol. 90, pages 5757-5761 (1993). The cell extract was solubilized in a buffer (10 mM Tris HCl, 0.15 M NaCl, 0.04 tiu aprotinin, 0.5% Nonidet-P40, pH 8.0) by centrifugation at 35,000 g for 30 minutes at 4 ° C (to remove cell debris) won.

Der DPP-IV Assay wurde wie folgt durchgeführt:
50 μl Substratlösung (AFC; AFC ist Amido-4-trifluormethylcoumarin), Endkonzentration 100 μM, wurden in schwarze Mikrotiterplatten vorgelegt. 20 μl Assay Puffer (Endkonzentrationen 50 mM Tris HCl pH 7.8, 50 mM NaCl, 1 % DMSO) wurde zupipettiert. Die Reaktion wurde durch Zugabe von 30 μl solubilisiertem Caco-2 Protein (Endkonzentration 0.14 μg Protein pro Well) gestartet. Die zu überprüfenden Testsubstanzen wurden typischerweise in 20 μl vorverdünnt zugefügt, wobei das Assaypuffervolumen dann entsprechend reduziert wurde. Die Reaktion wurde bei Raumtemperatur durchgeführt, die Inkubationsdauer betrug 60 Minuten. Danach wurde die Fluoreszenz in einem Victor 1420 Multilabel Counter gemessen, wobei die Anregungswellenlänge bei 405 nm und die Emissionswellenlänge bei 535 nm lag. Leerwerte (entsprechend 0 % Aktivität) wurden in Ansätzen ohne Caco-2 Protein (Volumen ersetzt durch Assay Puffer), Kontrollwerte (entsprechend 100 % Aktivität) wurden in Ansätzen ohne Substanzzusatz erhalten. Die Wirkstärke der jeweiligen Testsubstanzen, ausgedrückt als IC50 Werte, wurden aus Dosis-Wirkungs Kurven berechnet, die aus jeweils 11 Meßpunkten bestanden. Hierbei wurden folgende Ergebnisse erhalten:

The DPP-IV assay was carried out as follows:
50 μl substrate solution (AFC; AFC is amido-4-trifluoromethylcoumarin), final concentration 100 μM, were placed in black microtiter plates. 20 μl assay buffer (final concentrations 50 mM Tris HCl pH 7.8, 50 mM NaCl, 1% DMSO) were pipetted in. The reaction was started by adding 30 μl solubilized Caco-2 protein (final concentration 0.14 μg protein per well). The test substances to be checked were typically added prediluted in 20 μl, the assay buffer volume then being reduced accordingly. The reaction was carried out at room temperature, the incubation period was 60 minutes. The fluorescence was then measured in a Victor 1420 multilabel counter, the excitation wavelength being 405 nm and the emission wavelength 535 nm. Blank values (corresponding to 0% activity) were obtained in batches without Caco-2 protein (volume replaced by assay buffer), control values (corresponding to 100% activity) were obtained in batches without added substance. The potency of the respective test substances, expressed as IC 50 values, were calculated from dose-response curves, each of which consisted of 11 measuring points. The following results were obtained:
